Use after free in Dawn in Google Chrome on Mac prior to 150.0.7871.46 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Sandbox escape in Google Chrome on macOS (versions prior to 150.0.7871.46) stems from a use-after-free in Dawn, Chrome's WebGPU/graphics abstraction layer, and allows a remote attacker who lures a victim to a crafted HTML page to potentially break out of the renderer sandbox and gain higher-privileged code execution on the host. The flaw is rated High by Chromium and carries a CVSS 9.6 due to its network attack vector, low complexity, and scope change. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires the victim to open a crafted HTML page in a vulnerable Google Chrome build on macOS (versions before 150.0.7871.46), so user interaction (UI:R) is a hard prerequisite - the attack is not fully automatic or wormable. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The signals are mixed and worth contrasting. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker hosts or compromises a web page containing crafted JavaScript that drives the WebGPU/Dawn API into a use-after-free condition, then lures a macOS Chrome user to visit it (via phishing link, malvertising, or a watering-hole site). When the victim loads the page (satisfying the UI:R user-interaction requirement), the freed-object reuse is manipulated to corrupt GPU-process memory and escape the renderer sandbox toward higher-privileged execution. …
Remediation	Vendor-released patch: upgrade Google Chrome to 150.0.7871.46 or later on macOS, per the Chrome Stable Channel Update advisory (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html); Chrome's built-in updater will apply this automatically on relaunch, so ensure users fully restart the browser. … Detailed patch versions, workarounds, and compensating controls in full report.
